Shamrock Shenanigans Endurance Run

The Shamrock Shenanigans Endurance Run takes place at Union Meadows Park East in Douglassville, Pennsylvania. This event is a timed endurance race where participants complete as many loops as possible within a set timeframe. The course follows the berm trail, beginning and ending by the boat ramp.

The race is held on a loop measuring approximately 2.4 miles. The trail surface consists of packed gravel and features a wide, triple-track layout. Participants can choose between two primary time formats:

  • 5 hour endurance run
  • 10 hour endurance run

A stocked aid station is located near the start and finish area to support runners throughout their chosen duration. Every participant receives a long-sleeved race shirt, a race-themed sticker, and a race-themed reusable grocery bag. Finishers also receive a medal upon completing their event.

Registration includes the option to opt-out of the promotional merchandise, which reduces the registration fee. The event utilizes the natural layout of Union Meadows Park to provide a consistent running surface for the duration of the timed challenges.
